The Possible Effect of Steroids on Home Run Production
... Muscle mass and batted ball speed Tobin initially argues that a 10% increase in muscle mass leads to the batter supplying a 10% greater force to the bat, resulting in a 5% increase in bat speed. The argument is essentially one of energy conservation, where the work done by the batter in applying a f ...

... Gravitational PE is mgh, where height h is measured relative to some arbitrary reference level where PE = 0. For example, a book on a table has positive PE if the zero reference level is chosen to be the floor. However, if the ceiling is the zero level, then the book has negative PE on the table. On ...

... Brakes do work on wheels (you do work by pushing the brake pedal). When a car brakes, the work is the friction force (supplied by the brakes) multiplied by the distance over which the friction force acts. KE is transformed by work (friction) into thermal energy, sound energy and larger-scale vibrati ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
